Key Points of Course - Level 3

Your ability to understand the various types and the functions of standard equipment.
To see portable and stationary, automatic and manual types of equipment, application and use including bridges and manipulators and various transducers for A, B and C scan systems.

Information for general Theory of through and reflected transmission principles, single and double, straight and angle transducers. Couplants and wedges/shoes with basic knowledge of the cathode ray tube and screen displays and controls.

Only the two basic techniques of Contact and Immersion are required and used for this Level 3 course. The Phased Array Technique is provided for information purposes only.

Calibration requirements and methods with various blocks, steps and meters used. Reference standards and their vital role in Ultrasonic testing for industry needs.

Discontinuity and Defect identification including some sizing and location factors and object appraisal. The use of industry standards and their applicability to the test method.
